RAIL-JOINT.

SPECIFICATION forming part of I .etters Patent No. 402,402, dated April 30, 1889.

*i Application tiled August 13, 1888. Serial No. 282,670. (No model.)

ful Improvement in Rail-Joints, of which the following is a specification. n

This lnvention is an improvement in that class of rail-j oints in which a jacket is formed to receive the meeting ends of the rails and wedges are driven between said jacket and the base of the rails; and the present invention consists in .the novel .constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, 'Figure 1 is a perspective view of my improved joint. Fig. 2 is a side view thereof. Fig. 3 is a central cross-sec tion on about line Qc x, Fig. 2. Fig. 4 is a sectional plan view, and Fig. 5 a detail view, of one of the wedges.

In my present invention I have sought to provide a rail-joint goifered or corrugated in such manner as to form therecess for the wedges or' keys and at the same time have the met-al forming the walls of said recess of equal thickness throughout, and in which there will be provided a space within the jacket below the rails to take up the wear ofthe parts.

In carrying out the invention it is designed to roll the jacket out of metal of suitable thickness, goffering or corrugating it in such manner as to form the recesses for the wedges.

The jacket A, as shown, is formed of metal of equal thickness throughout, and is bent to form the base-plate l, the edge portions 2, at the edges of such base-plate, the goffers or corrugated portions 3, forming the walls of the wedge recesses, and the side plates, 4, the latter extending up and bearing snugly under the tread of the rail B, being provided at such end with anges or extensions 6, while below the base of such rail B, Iprovide a sufficient space at b to take up the wear at the upper edges of the side plates, 4. Notches or recesses 5 enable the proper turning of the nuts on the fastenin g-bolts. The goffers or corru gated portions 3 are inclined from end to end, forming the desi red tapered formation of thewedgerecesses, and it will be seen that t-he inclines at the opposite sides of the joint are reversedshaped or arched in cross-sectionand have suiiicient elasticity or spring to permit them to spread transversely as they are driven be tween the jacket and the' base of the rail. This lateral or transverse spreading of the Wed ges is effective and desirable, for the reason that it operates to secure the wedges or keys without giving to such parts any tendency to longitudinal movement and consequent loosening or displacement thereof. At the juncture of the goffers 3 and the side plates, 4, it will be seen that the jacket is bent to properly form the inner edge wall of the recess for the wedge or key.

The goifering or corrugating of thejacket Yis very importantas an element of strength, it serving in a large measure to strengthen the jacket and at the same time serving as the means for conveniently forming the recesses or ways for the wedges.

The space below the rails, in addition to taking up the wear, affords opportunity for a sufficient yielding or .spring to render the joint approximately elastic, and thus 'reduce the liability of breakage likely to occur where the joint isvrigid. At their upper ends the side plates Aor wings, 4, have lateral fianges or extensions 6, which fit under the tread of the rail, furnishing a broader bearing for such part.

Having thus described my invention, what I claim as new is* l. In a rail-joint, ajacket formed with a base-plate, l, goffers or corrugated portions 3, made of equal thickness throughout and inclined longitudinally, and side plates, 4, all substantially as set forth.

2. In a rail-joint, the combination, with the IOO rails and the jacket iitted thereon, of the wedges or keys curved or arched transversely, substantially as and for the purposes specified.

3. The inii rgved jacket for rail-joints, consisting of the base-plate '1, edge portions 2, sroters'or corrugated portions 3, made of equal thickness throughout and inclined Alongitudinally, the portions 23 on opposite sides being; inclined in reverse directions, and the side plates, t, all substantially as and fortlie purposes speciied.

1r. The combination of the rails, the jacket formed with base-plate l, edge portions 2, gotfers or corrugated portions 3, inclined troni
